How Can you tell the Difference between male and Female Guppies?

I have 2 Types of guppies, and 2 of each. i want to know if they are males, or females. One of them are Blue Variegated Guppy Fish and the other i have no clue what type it is. i really need your Help!
(One of the Blue Guppies is Big and one is small. One of them has black spots on it's sides and they are close to its head, any clue what that means?)

Male guppies are thinner, have longer and bigger top fins, and are normally prettier. They have a stick-like anal fin called a gonopodium.

Female guppies are fatter in the stomach area, have a fan/triangular shaped anal fin, and they have something called a gravid spot by their anal fin. Those are where her babies are. It will get darker as she grows more pregnant.
